Hello there members, I have a 454 that has these peanut port heads on it. I'm going to me using it for mud racing. This is my first year using a big block. Its all stock. But anyways I have a edelbrock performer oval port intake for it. I'm I going to have to gasket match the ports for this intake to work. I also have some truck pull headers for it that are coming out the hood that I had boughten. the ports on that are way bigger that the ones on the head. I have some aluminum header gaskets that are oval that are way to big too. I'm going to have to get the die grinder out and start opening up the heads. Any info will be appreciated. I found out about this peanut port thing after I ordered all this sh-t. So I would like to make it work. Thanks
